The following describes the embodiment with reference to the drawings. Figures 1 to 5 show a first embodiment of the building material for openings. This building material for openings is applied to sliding windows for residential use, and as shown in Figures 1 to 3, it comprises a frame 1 that is attached to an opening in the structural frame, and an outer screen 2 and an inner screen 3 that are provided within the frame 1 in a sliding manner so that they can be opened and closed freely.

As shown in Figures 1 to 3, the frame 1 is made up of an upper frame 4, a lower frame 5, and left and right vertical frames 6, 6 which are framed all around. The outer screen 2 and inner screen 3 are made up of an upper frame 7, a lower frame 8, a door end frame 9, and a joint frame 10 which are framed all around, with double-glazed glass 11 fitted inside. When the inner and outer screens 2, 3 are closed, the outer screen 2 is located on the left side when viewed from inside the room, and the inner screen 3 is located on the right side when viewed from inside the room. The outer screen 2 and inner screen 3 are locked with a crescent 12 installed on the joint frame 10.

As shown in Figure 4, the upper frame 4 has a screen rail 13 at its exterior end that supports the top of the screen (not shown), an outer rail 14 on the interior side of the screen rail 13 that supports the top of the outer screen 2, and an inner rail 15 on the interior side of the outer rail 14 that supports the top of the inner screen 3.
The upper frame 4 is made of an aluminum alloy extrusion and connects an exterior shape 16 and an interior shape 17 with a resin heat insulating bridge material 18, and covers the inner circumference of the interior shape 17 with a resin cover 19 to block heat transfer from the inside to the outside and prevent condensation on the inside. The resin cover 19 has an angle 21 that is screwed to the frame 20 as an integral part.
Furthermore, the upper frame 4 has a resin outer heat transfer suppression member 22 attached to the space between the outer rail 14 and the inner rail 15, and a resin inner heat transfer suppression member 23 attached between the inner rail 15 and the angle 21. The outer heat transfer suppression member 22 and the inner heat transfer suppression member 23 narrow the gap between the upper frame 4 and the inner and outer screens 2, 3, thereby further suppressing heat transfer in the indoor/outdoor directions.

4, the resin cover 19 integrally comprises an inner rail covering portion 24 that covers the interior side of the inner rail 15, an inner periphery covering portion 25 that covers the inner periphery side surface of the interior side shape member 17 of the upper frame 4, a contact portion 27 that protrudes indoors beyond the interior side shape member 17 of the upper frame 4 and contacts the body 26, and an L-shaped cross-section angle 21 that is provided hanging down below the contact portion 27. The contact portion 27 is formed in a hollow shape with a rectangular cross-section.
The resin cover 19 is attached to the upper frame 4 by engaging the locking portion 28 provided at the tip of the inner rail covering portion 24 and the locking portion 29 provided on the inner circumference covering portion 25 with the interior profile 17, and is fastened together with the upper frame 4 to the main body 26 with screws 30 from the inner circumference side.

As shown in Fig. 4, the outer heat transfer suppression member 22 has a plate-shaped portion 31 that covers the inner periphery of the exterior-side shape 16 and the insulating bridge material 18 of the upper frame 4, and a hollow portion 32 provided on the inner periphery of the plate-shaped portion 31. The hollow portion 32 is provided at a position closer to the interior side of the space between the outer rail 14 and the inner rail 15, and the left and right side walls 32a are bent inward in a V-shape to form an hourglass-shaped cross section. This allows the hollow portion 32 to be elastically deformable in the vertical direction. The lower wall 32b of the hollow portion 32 is horizontal and faces the upper ends of the outer screen 2 and the inner screen 3 with a gap of about 2 mm. The exterior end of the lower wall 32b has an abutment portion 33 that abuts against the upper end of the outer screen 2.
As shown in Figure 5, the upper frame 4 has a wind stop plate 34 provided between the outer rail 14 and the inner rail 15 at the central position in the longitudinal direction, and the outer heat transfer suppression member 22 is provided only on the side where the outer screen 2 is located to the left of the wind stop plate 34 when viewed from the inside of the room.
As shown in Figures 6 (a) and (b), the outer heat transfer suppression member 22 is freely attached and detached from the inner side of the upper frame 4 by engaging a locking piece 35 formed on the outdoor side end of the plate-shaped portion 31 with a groove 36 formed in the base portion of the outer rail 14, and by resilient claws 37 formed on the indoor side end of the plate-shaped portion 31 resiliently engaging with grooves 38 formed in the base portion of the inner rail 15.

As shown in Fig. 4, the inner heat transfer suppressing member 23 has a plate-shaped portion 39 that covers the inner periphery of the resin cover 19, and a hollow portion 40 provided on the inner periphery of the plate-shaped portion 39. The left and right side walls 40a of the hollow portion 40 are bent inward in a dogleg shape, forming an hourglass-shaped cross section. This allows the hollow portion 40 to elastically deform freely in the vertical direction. The bottom wall 40b of the hollow portion 40 is horizontal, and faces the upper end of the inner screen 3 with a gap of about 2 mm between them. As shown in Fig. 5, the inner heat transfer suppressing member 23 is provided over the entire longitudinal length of the upper frame 4.
6(a) and 6(b), the inner heat-transfer suppressing member 23 is detachably attached to the resin cover 19 of the upper frame 4 from the inner periphery side by engaging a locking piece 41 formed on the exterior side end of the plate-shaped portion 39 with a groove 42 formed in the base portion of the inner rail covering portion 24 of the resin cover 19, and by resilient claws 43 formed on the interior side end of the plate-shaped portion 39 resiliently engaging with grooves 44 formed in the base portion of the angle 21 of the resin cover 19. When the inner heat-transfer suppressing member 23 is attached to the resin cover 19, the screws 30 that secure the resin cover 19 to the frame 26 are hidden by the inner heat-transfer suppressing member 23.

7 shows the state when the inner screen 3 is set into the frame 1. As shown in the figure, the inner screen 3 is set between the inner rail 15 of the upper frame 4 and the inner rail 15 of the lower frame 5 from the inside of the room by pushing from above and below, as in the case of a normal sliding sash. At this time, the outer heat transfer suppressing member 22 and the inner heat transfer suppressing member 23 are elastically deformed so that the hollow portions 32, 40 are pressed against the upper end of the inner screen 3 and are crushed in the vertical direction, so that the outer heat transfer suppressing member 22 and the inner heat transfer suppressing member 23 do not get in the way of setting up the inner screen 3.
The outer screen 2 is fitted between the outer rail 14 of the upper frame 4 and the outer rail 14 of the lower frame 5 by pushing from above and below from the outside of the room, and at this time, the hollow portion 32 of the outer heat transfer suppression member 22 is pressed against the upper end of the outer screen 2 and elastically deformed, so that the outer heat transfer suppression member 22 does not get in the way of fitting the outer screen 2.
Even when the inner screen 3 and the outer screen 2 are removed from the frame 1 by vertically pushing them, the hollow parts 32, 40 are pressed by the upper ends of the screens 2, 3 and elastically deformed, so that the outer heat transfer suppressing member 22 and the inner heat transfer suppressing member 23 do not get in the way of removing the screens 2, 3.

In this way, the present opening building material has the outer heat transfer suppressing member 22 attached between the outer rail 14 and the inner rail 15 of the upper frame 4, and the inner heat transfer suppressing member 23 attached between the inner rail 15 of the upper frame 4 and the angle 21, and the outer heat transfer suppressing member 22 and the inner heat transfer suppressing member 23 narrow the gap between the upper frame 4 and the inner and outer screens 2, 3, thereby suppressing heat transfer in the indoor and outdoor directions from between the upper frame 4 and the inner and outer screens 2, 3, improving the insulation performance. Moreover, the present opening building material is easy to use because the hollow parts 32, 40 of the outer heat transfer suppressing member 22 and the inner heat transfer suppressing member 23 elastically deform in the vertical direction, so that the outer heat transfer suppressing member 22 and the inner heat transfer suppressing member 23 do not interfere with the installation and removal of the screens 2, 3.
The outer heat transfer suppression member 22 is provided at a position between the outer rail 14 and the inner rail 15, which is closer to the interior of the room, thereby reducing material costs while maintaining the function of suppressing heat transfer, thereby enabling costs to be reduced. In addition, the shoji screens 2 and 3 can be easily removed and attached.
In addition, this opening building material has a resin cover 19 that covers the indoor side of the upper frame 4 from the inner periphery, and the inner heat transfer suppressing member 23 is provided so as to be freely attached and detached from the inner periphery of the resin cover 19, so that the inner heat transfer suppressing member 23 can be easily attached and detached, and it is easy to use. Moreover, the screws 30 that secure the resin cover 19 to the building frame 26 are hidden by the inner heat transfer suppressing member 23, so the design is also good.
Since the resin cover 19 has an angle 21 integrally therewith, and the resin cover 19 has an abutment portion 27 which protrudes toward the interior of the room beyond the upper frame 4 and abuts against the main body 26, the resin cover 19 can effectively block heat transfer between the metal portion of the upper frame 4 and the interior of the room, thereby reliably preventing condensation on the interior side of the room.

As shown in Figure 4, the upper frame 7 of the outer screen 2 and the inner screen 3 is constructed by engaging and connecting an aluminum profile 45 arranged on the outside of the room and a plastic profile 46 arranged on the inside of the room. The aluminum profile 45 and the plastic profile 46 form a glass swallowing groove 47 that opens toward the inner periphery, and the upper edge of the double-glazed glass 11 is held in the glass swallowing groove 47 via a glass channel 48.
The resin profile 46 has a single hollow portion 49, and a rail receiving groove 50 that opens toward the outer periphery is formed by the exterior wall 45a of the aluminum profile 45 and the exterior wall 46a of the resin profile 46. The exterior wall 46a of the resin profile 46 has a recess 51 formed therein facing the rails 14, 15 of the upper frame 4.
A tension material holder 52 is formed on the upper end of the outdoor side wall 45a of the aluminum profile 45, and an outdoor side tension material (one-side tension material) 53 which is held by the tension material holder 52 and abuts against the outdoor side surfaces of the rails 14, 15 of the upper frame 4 is provided in the rail swallowing groove 50.
Further, in the rail swallowing groove 50, a mounting member 55 is attached, which is provided with an interior side tension material (other side tension material) 54 that abuts against the interior side surface of the rails 14, 15 of the upper frame 4. The mounting member 55 is provided over the entire length of the upper frame 7 in the longitudinal direction. The mounting member 55 is formed of an extruded aluminum alloy material, and has a substantially L-shaped cross section with a horizontal wall 56 and a vertical wall 57. The vertical wall 57 abuts against the interior side wall of the rail swallowing groove 50, and the horizontal wall 56 abuts against the bottom wall of the rail swallowing groove 50, and is fixed and attached with screws 58 from the outer periphery side. At the upper end of the vertical wall 57, a holding portion 59 that holds the base of the interior side tension material 54 is formed protruding toward the interior side, and the holding portion 59 enters the recess 51 of the resin shaped material 46.

As described above, this opening building material has high airtightness and sound insulation performance by providing an outside seal material 53 that abuts on the outside surface of the rails 14, 15 of the upper frame 4 in the rail swallowing groove 50 of the upper frame 7, and an inside seal material 54 that abuts on the inside surface of the rails 14, 15 of the upper frame 4, forming a double airtight line on both the outside and inside of the room. Specifically, the airtightness meets the highest grade A-4 of the grades A-1 to A-4 specified in JIS A 4706-2000.
Furthermore, even if the plastic profile 46 on the interior side of the upper frame 7 melts and is lost due to the heat of the fire during a fire, the metal mounting material 55 remains, preventing the upper frame 7 from coming off the rails 14, 15 of the upper frame 4, so this opening building material has fire resistance.
In addition, the mounting material 55 has a retaining portion 59 for the indoor side tension material 54, and the retaining portion 59 fits into a recess 51 provided in the upper frame 7, so that the groove width of the rail swallowing groove 50 in the upper frame 7 does not narrow even when the mounting material 55 is attached.

When such high airtightness is not required, as shown in Figure 8, the mounting material 55 with the indoor airtight material 54 is not attached to the rail intake groove 50 of the upper frame 7, but only the outdoor airtight material 53 is attached to the rail intake groove 50 of the upper frame 7. In this case, the airtightness will still be the same A-4 grade as when the mounting material 55 is attached, but the numerical value will be better when the mounting material 55 is attached, even within the same A-4 grade.

In this way, by choosing whether or not to attach the mounting material 55 with the indoor airtight material 54 in the rail-swallowing groove 50 of the upper frame 7, it is possible to manufacture opening building materials with different airtightness performance, which makes assembly easy.

As shown in Figure 2, the door frame 9 of the outer shoji screen 2 is constructed by engaging and connecting an aluminum profile 60 arranged on the outside of the room with a plastic profile 61 arranged on the inside of the room, and a handle 62 is recessed into the interior side of the plastic profile 61 and is formed over the entire length in the longitudinal direction.

As shown in Figure 2, the vertical frame 6 on the outer shoji screen 2 side, located on the left side when viewed from inside the room, has a resin vertical frame cover 63 attached to the interior side, which covers the inner peripheral side of the vertical frame 6. The vertical frame cover 63 has a hollow section 64 divided into multiple rooms, and has an angle 21 that is screwed to the frame 20 as an integral part. By attaching the vertical frame cover 63 in this way, the insulation performance is improved and condensation on the interior side is prevented. Also, by attaching the vertical frame cover 63, the part of the door end frame 9 that is on the outer periphery side of the glass support piece 65 when viewed from inside the room is hidden by the vertical frame cover 63.

The vertical frame cover 63 has a step 66 that opens toward the inner periphery and the outside of the room, and a finger insertion space 67 for inserting fingers when placing a hand on the handle 62 of the door end frame 9. Furthermore, a soft inner peripheral side wall 68 is formed to protrude from the inner periphery of the vertical frame cover 63 toward the door end frame 9, and the finger insertion space 67 is hidden by the inner peripheral side wall 68.
When opening the outer shoji screen 2, as shown by the phantom lines in Figure 2, the inner side wall 68 of the vertical frame cover 63 is pushed with the tip of a finger to deform it toward the outer periphery, and a finger is inserted into the finger insertion space 67, and the finger is then hooked onto the handle portion 62 of the door end frame 9 to open the outer shoji screen 2.

In this way, this opening building material is easy to use because by attaching the vertical frame cover 63 to the interior side of the door frame 9, the outer screen 2 can be opened and closed without any problems by deforming the inner peripheral side wall 68 of the vertical frame cover 63, even if the handle portion 62 of the door frame 9 is hidden. Furthermore, by attaching the vertical frame cover 63, insulation is improved, and by hiding the door frame 9 with the vertical frame cover 63, the interior design and visibility are improved.

9 and 10 show modified examples of the vertical frame cover 63. In the example of Fig. 9(a), a retaining groove 69 is formed on the exterior side surface of the step portion 66 of the vertical frame cover 63, and a separate inner peripheral side wall 68 formed in a hollow shape from rubber or the like is provided and held in the retaining groove 69, thereby hiding the finger insertion space 67. According to this example, the inner peripheral side wall 68 is removable, making maintenance easy.
In the example of Fig. 9(b), the inner peripheral side wall 68 of the vertical frame cover 63 is formed into a hollow shape having a substantially right-angled triangular cross section, and the hypotenuse is bent inward. According to this example, even if the inner peripheral side wall 68 is repeatedly deformed, the original shape can be maintained.
In the example of Figure 10(a), an inner peripheral side wall 68 formed as a separate part is attached by engaging an engagement piece 70 formed on the inside end of the room with a groove 71 provided in a step 66 of a vertical frame cover 63, and the inner peripheral side wall 68 is deformed so as to tilt toward the outer periphery with the engagement piece 70 as a fulcrum, allowing the handhold 62 of the door end frame 9 to be placed on it. The inner peripheral side wall 68 is biased toward the inner periphery by a rubber piece 72 provided on the outer periphery.
In the example of Fig. 10(b), the inner peripheral side wall 68 is formed as a separate part from the vertical frame cover 63, and the inner peripheral side wall 68 is deformed so as to move parallel to the outer periphery, so that the handhold 62 of the door end frame 9 can be placed on it. The inner peripheral side wall 68 is biased inward by a sponge 73 provided on the outer periphery.
In the example of Fig. 10(c), the inner circumferential side wall 68 is formed as a separate part from the vertical frame cover 63, and the inner circumferential side wall 68 is deformed so as to tilt toward the outer periphery with the inside end as a fulcrum, allowing the handhold 62 of the door end frame 9 to be placed on it. The inner circumferential side wall 68 is biased toward the inner periphery by a sponge 73 provided on the outer periphery.

As shown in Figure 2, the door frame 9 of the inner shoji 3 is constructed by engaging and connecting an aluminum profile 74 arranged on the outside of the room and a plastic profile 75 arranged on the inside of the room, and a handle portion 76 is formed at the inner end of the plastic profile 75 so as to protrude toward the inside of the room.
The vertical frame 6 on the inner shoji 3 side, located on the right side as viewed from inside the room, has a resin vertical frame cover 77 attached to the inside of the room, which covers the inner peripheral side of the vertical frame 6. The vertical frame cover 77 has an angle 21 integral with it that is screwed to the frame 20. As with the outer shoji 2 side, the door end frame 9 of the inner shoji 3 is hidden by the vertical frame cover 77 on the outer peripheral side of the glass support piece 65 as viewed from inside the room.

Fig. 11 shows a second embodiment of the opening construction material. The upper frame 4 has an outer screen guide groove 78 that guides the upper part of the upper frame 7 of the outer screen 2, and an inner screen guide groove 79 that guides the upper part of the upper frame 7 of the inner screen 3, and a resin cover 19 is attached to cover the inner screen guide groove 79 from the inner periphery side.
Within the outer screen guide groove 78 and inner screen guide groove 79 of the upper frame 4, outdoor side tight material (one-side tight material) 53 is provided hanging down from the bottom wall of the outer screen guide groove 78 and inner screen guide groove 79 to seal the gap between the outer screen guide groove 78 and the upper frame 7 of the outer screen 2, and the gap between the inner screen guide groove 79 and the upper frame 7 of the inner screen 3, respectively, at an outdoor side position.
Furthermore, within the outer screen guide groove 78 and inner screen guide groove 79 of the upper frame 4, an interior side tight material (other side tight material) 54 which seals the gap between the outer screen guide groove 78 and the upper frame 7 of the outer screen 2, and the gap between the inner screen guide groove 79 and the upper frame 7 of the inner screen 3, respectively, at the interior side, is provided hanging down from mounting material 55 which is fixed to the bottom wall of the outer screen guide groove 78 and inner screen guide groove 79 with screws 58.

This opening building material has an exterior seal material 53 and an interior seal material 54 provided in the exterior screen guide groove 78 and the interior screen guide groove 79 of the upper frame 4, respectively, and forms a double airtight line on the exterior and interior sides between the upper frame 4 and the interior and exterior screens 2, 3, allowing it to exhibit high airtightness and soundproofing performance.

If such high airtightness is not required, as shown in Figure 12, the mounting material 55 with the indoor airtight material 54 is not attached to the outer screen guide groove 78 and inner screen guide groove 79 of the upper frame 4, and only the outdoor airtight material 53 is provided in the outer screen guide groove 78 and inner screen guide groove 79 of the upper frame 4.

In this way, by choosing whether or not to attach the mounting material 55 with the indoor airtight material 54 in the outer screen guide groove 78 and inner screen guide groove 79 of the upper frame 4, it is possible to manufacture opening building materials with different airtightness performance, which makes it easy to assemble.

As described above, this opening construction material (first embodiment) comprises an upper frame 4 and heat transfer suppressing members 22, 23. The upper frame 4 has an outer rail 14 that supports the outer screen 2, an inner rail 15 that supports the inner screen 3, and an angle 21. The heat transfer suppressing members 22, 23 are made of resin and deform in the vertical direction so as not to interfere with the removal and installation of the screens 2, 3. The outer heat transfer suppressing member 22 is provided only on the outer screen 2 side between the outer rail 14 and the inner rail 15. The inner heat transfer suppression member 23 is provided between the inner rail 15 and the angle 21 over approximately the entire length of the upper frame 4, and the outer heat transfer suppression member 22 and the inner heat transfer suppression member 23 narrow the gap between the upper frame 4 and the inner and outer screens 2, 3 (see Figure 4), so that the heat transfer suppression members 22, 23 do not get in the way when removing and attaching the screens 2, 3, making it easy to use, and further, narrowing the gap between the upper frame 4 and the inner and outer screens 2, 3 by the outer heat transfer suppression member 22 and the inner heat transfer suppression member 23 improves the insulation performance.
The heat transfer suppression member (inner heat transfer suppression member) 23 is attached to the upper frame 4 from the inner periphery so as to be freely attached and detached. Since the heat transfer suppression member 23 hides the screws 30 that attach the upper frame 4 to the main body 26, the heat transfer suppression member 23 can be easily attached and detached for good usability, and since the screws 30 that attach the upper frame 4 to the main body 26 are hidden, the design is also good.
The upper frame 4 has a resin angle forming member (resin cover) 19 on the indoor side, and the inner heat transfer suppression member 23 is attached to the angle forming member 19 so as to be freely attached and detached from the inner side, so that the inner heat transfer suppression member 23 can be easily attached and detached, making it easy to use and improving the insulation performance.
The outer heat transfer suppression member 22 is provided at a position between the outer rail 14 and the inner rail 15, which is closer to the interior of the room, thereby reducing material costs while maintaining the function of suppressing heat transfer, thereby enabling costs to be reduced. In addition, the shoji screens 2 and 3 can be easily removed and attached.

This opening building material (first embodiment) comprises a frame material (upper frame) 4, a resin cover 19, and a heat transfer suppressing member (inner heat transfer suppressing member) 23, the resin cover 19 covers the frame material 4 from the inner periphery side, the heat transfer suppressing member 23 narrows the gap between the frame material 4 and the shoji (inner shoji) 3 supported by the frame material 4, and is provided so as to be freely attached and detached from the inner periphery side of the resin cover 19, and the heat transfer suppressing member 23 hides the screws 30 attaching the resin cover 19 to the frame 26 (see FIG. 4), so that the heat transfer suppressing member 23 can be easily attached and detached, and is easy to use, and since the screws 30 attaching the resin cover 19 to the frame 26 are hidden, the design is also good. Moreover, by covering the frame material 4 from the inner periphery side with the resin cover 19 and providing the heat transfer suppressing member 23 on the inner periphery side of the resin cover 19 to narrow the gap between the frame material 4 and the shoji 3, the insulation performance is improved.

The resin cover 19 has a contact portion 27 that protrudes toward the inside of the room beyond the frame material 4 and abuts against the main body 26, thereby blocking heat transfer between the inside of the room and the frame material 4, further improving the insulation performance.

The manufacturing method of this opening building material (first embodiment) comprises an upper frame 4 and an upper frame 7, the upper frame 4 having rails 14, 15, the upper frame 7 having a rail swallowing groove 50 that swallows the rails 14, 15, and a one-side airtight material (outdoor airtight material) 53 that abuts against one side of the exterior or interior side of the rails 14, 15 is attached within the rail swallowing groove 50, and by selecting whether or not to attach a mounting material 55 having an other-side airtight material (indoor airtight material) 54 that abuts against the other side of the rails 14, 15 to the rail swallowing groove 50, opening building materials with different airtightness performance can be manufactured (see Figures 4 and 8), making it easy to assemble.
The mounting material 55 is made of metal, and by mounting it in the rail swallowing groove 50 of the upper frame 7, even if the resin shape material 46 of the upper frame 7 melts and is lost in the event of a fire, the metal mounting material 55 remains and gets caught on the rails 14, 15, preventing the screens 2, 3 from coming off.
The mounting material 55 has a retaining portion 59 for the other side tension material 54, and the retaining portion 59 fits into a recess 51 provided in the upper frame 7 (see Figure 4), so that the groove width of the rail-engaging groove 50 in the upper frame 7 does not narrow even when the mounting material 55 is attached.
The manufacturing method of this opening building material (second embodiment) comprises an upper frame 4 and an upper frame 7, the upper frame 4 having grooves (external screen guide groove 78, inner screen guide groove 79) that guide the upper part of the upper frame 7, and a one-side airtight material (outside airtight material) 53 that seals the gap between the grooves 78, 79 of the upper frame 4 and the upper frame 7 on one side, either the outside or the inside of the room, is attached into the grooves 78, 79 of the upper frame 4, and a mounting material 55 having a other-side airtight material (inside airtight material) 54 that seals the gap between the grooves 78, 79 of the upper frame 4 and the upper frame 7 on the other side can be selected to be attached or not attached into the grooves 78, 79 of the upper frame 4, thereby making it possible to manufacture opening building materials with different airtightness performance (see Figures 11 and 12), and thus making it easy to assemble.

This opening building material (first embodiment) comprises a door end frame 9 and a vertical frame cover 63 located on the interior side of the door end frame 9, the vertical frame cover 63 having a finger insertion space 67 for inserting fingers when placing hands on the door end frame 9 and an inner peripheral side wall 68 that hides the finger insertion space 67, and by deforming the inner peripheral side wall 68 so that hands can be placed on the handle portion 62 of the door end frame 9, the shoji (outer shoji) 2 can be easily opened by placing hands on the handle portion 62 of the door end frame 9, making it easy to use. Moreover, by providing the vertical frame cover 63 on the interior side of the door end frame 9, heat insulation performance is improved.
The vertical frame cover 63 has a step 66 that opens toward the inner circumference and the outside of the room, and the end frame 9 has a recessed handle 62 on the indoor side, making it easy to place your hand on the handle 62 of the end frame 9, improving the operability of the shoji screen 2.
The vertical frame cover 63 is made of resin, and the inner side wall 68 is soft and protrudes from the inner side of the vertical frame cover 63 toward the door frame 9, thereby ensuring good operability of the shoji screen 2 while preventing condensation on the inside of the room.
